To Upgrade the Base Management Feature on a Server

This procedure describes how to upgrade the base management feature on a server. This procedure is only necessary after upgrading the N1 System Manager from a previous release, for managed servers that still run the earlier version of the base management feature included N1 System Manager 1.1 or Sun Management Center 3.5.1. This procedure is for individual servers. You can upgrade the base management feature on multiple servers at once. See Chapter 3, Upgrading the Sun N1 System Manager Software, in Sun N1 System Manager 1.3 Installation and Configuration Guide for details.

Note –

If the server was freshly installed using the load server or load group commands from the latest version of the N1 System Manager, and the feature subcommand was used with the update keyword, this procedure is not necessary.

Use the add server feature basemanagement command with the upgrade keyword to upgrade a managed server to a new version from the existing base management feature.

If you submit add server feature commands by using a script, see Example 6–4 for an example.

Before You Begin

Discover servers. See Chapter 4, Discovering Manageable Servers.
This base management feature upgrade procedure applies to managed servers on which the base management feature is already installed by a previous version of the N1 System Manager.

Steps

To upgrade the base management feature, type the following command:
N1-ok> add server server feature basemanagement upgrade
An Add Base Management Support job starts.

See add server in Sun N1 System Manager 1.3 Command Line Reference Manual for details about command syntax.

Track the Add Base Management Support job to completion.

After the job completes successfully, the show server command output for the server appears with the OS Monitoring Supported value as OK. In addition, the Base Management Supported column on the Server Details page is marked as Yes. See Enabling and Disabling Monitoring for a graphic that shows this.

Troubleshooting

Adding the base management feature might fail due to stale SSH entries on the management server. If the add server feature osmonitor agentip command fails and no true security breach has occurred, remove the known_hosts file or the specific entry in the file that corresponds to the managed server. Then, retry the add server feature osmonitor agentip command. See To Update the ssh_known_hosts File in Sun N1 System Manager 1.3 Troubleshooting Guide for details.

The problem of stale SSH entries on the management server can be avoided if, during the n1smconfig configuration process, you modify SSH policies by accepting changed or unknown host keys. Accepting changed or unknown host keys carries a security risk but avoids the problem of stale SSH entries on the management server.
